Advanced Simulation Library (ASL) is free and open source hardware accelerated multiphysics simulation software. It enables users to write customized numerical solvers in C++ and deploy them on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs[1] up to heterogeneous clusters and supercomputers. Its internal computational engine is written in OpenCL and utilizes variety of advanced numerical methods,[2] i.a. Finite Difference, Lattice Boltzmann, Immersed Boundary. ASL can be used to model various coupled physical and chemical phenomena, especially in the field of Computational fluid dynamics. It is distributed under the free GNU Affero General Public License with an optional commercial license.

History

Advanced Simulation Library is being developed by Avtech Scientific, an Israeli company. Its source code was released to the community on 14 May 2015 whose members packaged it for scientific sections of all major Linux distributions shortly thereafter.[3][4][5][6][7][8] Subsequently Khronos Group and IWOCL acknowledged the significance of ASL and listed it on their websites among OpenCL-based resources.[9][10]

Application areas

Advantages and disadvantages

Advantages

  • Easy to learn C++ routines[11] (no OpenCL knowledge required)
  • High performance[12]
  • Ability to run applications on a variety of parallel architectures
  • Automatic parallelization of applications
  • Ability to deal with complex boundaries
  • Ability to incorporate microscopic interactions

Disadvantages

  • Absence of detailed documentation (besides the Developer Guide generated from the source code comments)
  • Not all OpenCL drivers are mature enough for the library[13]

Features

ASL provides a range of features to solve number of problems - from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid mechanics and elasticity.[14]
